ROUBLESHOOTING
The purpose of this chapter is to provide DCSI customers with procedures that will
assist in determining if a failed meter issue can be resolved in TNS or if a field visit
is required. It is useful for installers and meter shop personnel.
assist in determining if a failed meter issue can be resolved in TNS or if a field visit
is required. It is useful for installers and meter shop personnel.
A failed meter or a meter with an invalid response can be the result of several
factors including process, software, or hardware. The following sections provide
steps for, first, trying to identify the problem in TNS (Complete the steps in
Performing Remote Analysis (TNS)), and then conducting a field visit if necessary.
If a field visit is required, proceed to Field Troubleshooting on page 38. Follow
the instructions in Meter Shop Test System on page 39 if the TNS analysis and field
visit steps do not correct the problem.

The UMT-C-KV may spontaneously draw a current surge if TWACS inbound
communication takes place during the test. This may affect the test equipment or
results. This can only occur when the SCE sends an outbound command requesting
a response from the UMT-C-KV.

Performing Remote Analysis (TNS)
Complete the following steps to determine if a field visit is required for an
unresponsive meter. You can end the procedure at any step and correct the problem
when a cause of failure is determined.

1.
Check the AMRCOMMFAIL table for TWACS serial numbers that have
excessive AMR Communication Failure counts. This enables you to
identify meters that are consistently failing AMR.
excessive AMR Communication Failure counts. This enables you to
identify meters that are consistently failing AMR.
If the meter fail count in the AMRCOMMFAIL table is equal to or greater
than the MaxFailCnt in the TNSDEFAULTS table, the Quality Code (QC)
will be set to RO (Retry Override). When the quality code is RO, the meter
unit map will have changed in the AMRCMDLST2WAY table. The meter
will be attempted the first time, but will not be issued subsequent retries and
must be read manually.
